I would also like to measure frequency (50-400hz) as well, I'm still working that bit out, size is another bigger factor I'm planning on putting this inside a wooden bee hive, so it will be sealed and I'm hoping to make it fairly discrete to the bees.

Hello All,
I understand that this is a very simple question, and I think I've figured it out, but want to be sure I'm not missing something. I'm working on a project for a programming class and need to monitor temperature in a sealed environment. This will be battery operated so the low power features of the Anarduino chips are what drew me here. It looks like the CW-915 matches my needs and then some, there's also the example which appears to do exactly what I'm looking for, but I wanted to ask, being that I only need temperature and no other inputs, is there a better chip for my application that I'm missing?
Thank you,
cbanta
